General overhaul of Tost releases

Please find here some important hints regarding
the overhaul of releases in our works

Important information – please always indicate

• In which type of glider is the release installed?
• Position of the lever
• Any abnormalities during operation
• Delivery address – if different from invoice address
• Complete contact data: phone, fax, email
• Please indicate the way payment you prefer

You can also use the order form

The overhaul will take approx. 2 weeks

valid from July 2001

TBO 2000 launches accordingly 10.000 actuations

Life limiting part is the release spring, with a life expectancy of about 10.000 actuations. With about 5 actuations in normal flight operation - like in Germany - this is, as before, 2000 launches.

Should you have more actuations per launch in pure training operation the TBO is reduced accordingly (e. g. with 8 actuations per launch the TBO would be 1250 launches).

If you have only 2 actuations per launch, the TBO consequentially would be 5000 launches.

This decision – after how many launches the 10.000 actuations are accomplished – is in the responsibility of the aircraft holder.

If both releases are actuated together (like in Germany) both releases have to be sent for overhaul after having performed the adequate number of launches.

The life limit of 4 years is replaced by a manufacturer's recommendation.

The new regulation had been published from the LBA in the "NfL" on July 12, 2001 and therefore is valid right now.

Please note that the new regulation can be applied only to releases which had a valid certificate in 2001!

For your documentation, you can print the following documents (see right hand):

valid Nfl II - 16/02
Technische Mitteilung TM 1-2001
LTA Nr. 1989 - 018/3, published from LBA on 02.05.2002
Technische Mitteilung Nr. 60.230/2-4/88

Revision of Operating Manual of Tost Releases

In the documents of the glider must be included an Operating Manual of the release in the latest revision. This requirement from EASA results from the new maintenance programs.

Please see the table for the number of revisions for each release type.

Operating Manual Type of release	Date of first issue	Revision No.	Date of last revision
E 72 / E 75	March 1989	4	March 2001
E 85	March 1989	4	March 2001
E 22	Oct 2002	1	May 2003
G 72 / G 73	Jan 1989	3	March 2001
G 88	Feb 1989	3	March 2001
S 72 / SH 72	July 1989	3	March 2001

Please note: if you are not in the possesion of an Operating Manual of the latest revision, we can send you this document. But this is only possible when the release is airworthy. We can check this with the help of the serial number of your release: we refer to the life file of the release and its filed service condition.

This service (sending od new Operating Manual and/or new EASA FORM 1) will be charged.
